I recommend this eyepiece for its sturdy construction and beautiful images. This eyepiece is easy to apply to the scope, has a crisp, wide field of view and is delightful to use. In low light, the colors are fantastic (I use it with an 85mm scope). The eye cup is easy to move in and out.

I had this same eyepiece for 5 years previous to purchasing this one. However, that eyepiece fell off with heavy use and was lost in tall grass. (I conduct bird research and use the scope daily between March and August.) This new eyepiece feels like it has a little extra tension at the end of the tightening ring, so it feels like it will not fall off again. However, if you are really worried about it, there is another eyepiece with a locking ring (or do what I do and insure the equipment).
